Hi guys
I'm working on a 05 Bonneville sle 3.8 na 4t65e. I'm wanting to up the line pressure in the trans and i think this is the right table but the psi in the table doesn't make sense. With a mechanical gauge on the trans main line pressure is way over these psi numbers, over 200 depending on current. Any help would be great..Thanks
